phone-number

问题 I'm trying to validate my form. In my form is a phone number field. The user inserts a phone number and validation takes place as well as formatting. I've read a lot of the other similar questions in StackOverflow and through searches elsewhere, but I'm stuck. The form keeps saying that a valid number I insert is invalid. I'm only concerned with NANP numbers and I understand the NANP numbers are formatted like this: NXX-NXX-XXXX, where N can only be digits [2-9] , and X can be [0-9] . I don't

问题 I need to get the number that I am calling from my Android device programmatically. What I'm doing now is the following: I listen for android.intent.action.PHONE_STATE being broadcasted which means that either I am being called or am calling (or receiving an SMS etc). In a BroadcastReceiver I retrieve the extra incoming_number from the intent. Sadly I cannot get the number which is being called if I initiate the call though. How can I do this? 回答1: You need to use the Intent android.intent

问题 What can I do to comprehensively validate an Australian Phone Number? I need this for an application I'm writing. You can assume it is dialed from within Australia.
